* Initialize the Virtual Memory subsystem.
* vm_init initializes the virtual memory system.
* This is done only by the first cpu up.
* The start and end address of physical memory is passed in.
extern vm_offset_t avail_start, avail_end;
extern vm_offset_t virtual_avail, virtual_end;
* Initializes resident memory structures.
* From here on, all physical memory is accounted for,
* and we use only virtual addresses.
virtual_avail = vm_page_startup(avail_start, avail_end, virtual_avail);
* Initialize other VM packages
